This is a GUI frontend for the PSRayTracing implementation of the "Ray Tracing in One Weekend" books by Peter Shirley (and others). Which renders the images in the book faster than the reference code, but also offers other features (e.g. threading, render progress, toggle-able and more). The source code for this program, as well as a report auditing all of the changes/improvements, is freely available at: https://github.com/define-private-public/PSRayTracing

Verdict
The clearest difference is update cadence: GroMoC mobile at every 12 months against PSRayTracing's every 30 months. GroMoC mobile also leads on iOS requirement (13.0 vs 17). On price, ads, in-app purchases and device support there is nothing between them.
